Specification of Letters Patent. Application filed November 25, 1911.Serial No. 662,270.

Patented Sept. 10, 1912.

strapping all the desired localities of a box' may be unwound. from thereel, measured off, and cut off all at the same time. In such a packagein which a plurality of surface overlying strips are first combined as aunit or part and are then wound into a single package or coil, it isnecessary merely to measure off the desired length along the surf-ace ofthe top or exposed strip so that this top or exposed strip so measureddoes itself serve as a lineal measurer for all the strips of said set.Also if the package is to be self-measuring so as not to require theapplication thereto of a separate measuring device it is necessary toapply measuring marks only tothe outer or exposed strip of said set,which does then, in the same way as if measured off by a separatemeasuring device, itself serve as a lineal measurer for all thestrips ofsaid set.

In packages of the above type, it has been found that there is atendency for one or more of the strips of a set to unwind from the coilindependently of the others of the set. In other words, there has been atendency for the set of strips wound as a unit to separate so that theends of the Strips projecting from the coil are of materially unequallength so that it is then inconvenient to cause a single exposed stripof a set to serve as a lineal measurer for all the strips of said set.

An object of the resent invention is to combine with such a plural-strapcoil means for maintaining the unity of the set of a plurality of strapsand at the same time to permit the desired lengths of such a set to beunwound from and drawn out from the coil with ease and quickness; and tohold the severed ends of the strips from drawing jaws which pivotmounting on the frame.

means causes these jaws to grip the pluralback and flying apart todestroy the integrity of,the set. herein as a feeding clip supported bya framework sustaining the coil and mounted ona pivot transverse to thecoil. The feeding clip comprises preferably a pair of gripping rojectoutwardly from their Spring ityof straps at a locality outside of thecli bearingand lateral confining ears are pre erably formed on the jawsto prevent the lateral displacement of the plurality of straps.

In the embodiment of the invention which comprises apan-cake structurewith all the straps of the coil superposed the feeding clip is itselffixed against lateral movement, while in the embodiment of the inventioncomprising a reelwound with a set of plurality of straps so that thecoil occupies a space several times the width of a single set of straps,the feeding clip is mounted so as to have an independent lateralmovement along an extensive pivot bearing in the form of a cross rod.

The above and further objective featuresof the invention will be setforth more fully in the accompanying claims which should be read inconnection with the following specification, which. describes theillustrative embodiments of the invention shown in the accompanyingdrawings, which form a part of this application in which, likecharacters designate corresponding parts, and in,

which '55 This means is embodied Figure l is a side elevation with partsbroken away of the structure comprising a reel in its embodiment; Fig. 2is a plan view of the structure shown in Fig. 1; Fig. 3 is a sideelevation drawn to an enlarged scale of the feeding clip of theembodiment of Fi 1 and showing its relation to a set of two straps; Fig.1 is a plan view of the apparatus shown in Fig. 3; Fig. 5 is a sideelevation of a pan-cake-like coil of a set of two straps and embodyingthe invention; Fig. 6 is a plan view of the structure shown in Fig. 5;Fig. 7 is a side elevation showing a modified embodiment of theinvention applied to a pan-cake-like coil such as is shown in Fig. 5;Fig. 8 is a horizontal section alon line VIII-VIH of Fig. 7 with theco'i omitted; and Fig. 9 is a View corresponding to Fig. 3, but showingthe clockwise rotation of the clip F, and the consequent kinking of thestraps 1 and 2.

Referring first to the structure shown in Figs. 1 to 4 inclusive, a setA of a plurality of straps 1 and 2 of strap iron are wound on to thereel B to formthe coil C, which coil has a thickness or width severaltimes the width of the individual set of straps A. The reel B is shownsustained by a frame D of suitable material such as wood through themedium of the spindle 3. The bottom of the frame D 1s a box-likestructure 4 to the sides of which two spaced uprights 5 and 6 aresuitably secured. Stays 7 and 8 extending forwardly from the spindlesupports 9 and 10 are secured to the uprights 5 and 6' to brace thesame. A cross rod 11 is mount-' ed horizontally in the upper ends in theuprights 5 and 6 so as to extend crosswise of the reel C. This rodserves as a clip-bear-i ing. Upon this clip bearing 11 is mounted thefeeding clip F. The feeding clip F comprises a pair of 15 and 16 arestruck-up at right angles and are perforated to receive the shortbearing tube 17. The rear of the gripping jaw 14 The spring means, shownas the wire spring 21, encircles the projecting ends of the tube 17after first passing under the jaw 13 and then terminates over the jaw 14so as to cause the jaws 13 and 14 to grip the set of straps A at thelocality of the ears 19 and 30 which is considerably forward of thebearing 22 formed by the tube 17 on the cross rod 11, so that the clipmay have free pivotal movement on the rod 11 andalso free lateral playthereon to accommodate itself to the varying lateral position of the setin the reel B,

be seen that the set of straps A pass some what to one side, that isbelow the cross rod 11, while the gripping locality ofthe feeding clip Fis well forward of this cross rod 11. When the set of straps .A ispulled out from the feeding clip F, the friction of the clip upon theset of straps being at the forward end of the clip, tends to hold theclip substantially parallel with the set of straps, and therefore,possesses little or no retarding force to the withdrawal of the set ofstraps. On the other hand when the set of straps has been cut offforward of the clip gripping jaws 13 and 14. At the rear of the jaw 13 apair of wingsof straps A with-. j which set weaves from side to. sidethroughout the width of the coil 0.

From an inspection of the figures it will F, as is the practice,

the end ofthe said straps A through the clip F is effectually prevented.This withdrawal movement tends to rotate the clip F clockwise about thebearing rod 11 so that the sharp shoulder 24 of the lower jaw member 13is moved against the lower strap to grip the same so that there is atendency to form a kink in the set of straps to prevent theirwithdrawal, see Fig. 9.

In the structure just described, the uprights 5 and 6 and the braces 7and 8 which combine the clip-bearing 11 with the frame D which sustainsthe coil 0 may be shipped from the factory as an integral part of thedispenser or not according to convenience. The attaching means for theseparts are shown as screws to permit of their ready mounting and removaland so as to facilitate shipment knocked down.

Figs. 5, 6, 7 and 8 show the feeding clip F in combination with a pancake like coil of a plurality-set of straps, previously referred toherein and of the kind claimed in my Patent No. 1,004,028, grantedAugust 19, 1911, for metallic shipping packages.

In the embodiment shown in Figs. 5 and 6, the set A- of two straps iswound into a compact pan-cake like structure C upon the wooden disk Bwhich forms a central pivotal bearing for the bolt 3 strap-iron yoke 25diametrically looped about the coil C. Two radial arms 26 and 27 arealso pivotally secured by the bolt 3, their outer ends beingcross-connected by the clip bearing bolt 28, which serves as thepivot-bearing for the clip F and also pierces the ends of the adjustablebrace rods 29 and 30. The rear ends of the brace rods 29 and 30 areprovided each with a series of relatively crossed spaced perforations31. The upper portion of the loop strap 25 is likewise provided withcorresponding opposed perforations 32, so that a nail or bolt 33 may bepassed through the perforations 32 and a set of the perforations 31 forthe combined purpose of securing the yoke 25 to a ost or wall and offixing the brace rods 29 and 30. When the coil C is comparatively fullthe adjustment of the parts should be that shown in Fig. 5. As the set Aof straps is unwound from the coil C, it has been found advisable toreadjust the brace rods 29 and 30 by securing them to the bolt 33through the medium of a set of perforations 31 nearer to the rear end ofthe brace bars 29 and 30, so that the feeding clip F is lowered tocorrespond with the lowering of/the upper limit of the coil C due tounwinding.

In Figs. 7 and 8 the radial supporting rods 26 and 27 for the feedingclip and also the brace rods 29 and 30 have been elimiwhich clamps the,

nated. In this embodiment the yoke 25 of comparatively stiff strap ironfinds its embodiments in the yoke 25, the upper portions of which, areprovided with opposing vertical slots 35 and 36, in which the ends ofthe pivot bolt 38 serving as a pivot bearfor the clip F are looselymounted so medium of the rods or arms 26, 27 29 and 30 and the slot 35.

It is preferred that the clips F and F be formed of sheet metal such assheet iron or sheetsteel.
